A return value of "1" indicates that the device is online, while a return value '0' indicates that the device
is offline.

# cat ­/sys/bus/ccwgroup/drivers/qeth/0.0.0600/if_name

Now you need to create the configuration file for your new interface. The network interface
configuration files are placed in
/etc/sysconfig/network-scripts/
.
The network configuration files use the naming convention ifcfg-
device
, where device is the value
found in the
if_name
file in the qeth group device that was created earlier. In this example it is
eth1
.
